BED-BOTTOM.

Specification of Letters Patent.

Patented Oct. 18, 1910.

Application filed April 27, 1910. Serial No. 557,991.

To all whom it may concern:

Be it known that we, HERMAN D. SWEIN- HAGEN and FRANK A. THEOBALD,citizens of the United States, residing at Napoleon, in the county ofHenry and State of Ohio, have invented certain new and usefulImprovements in Bed-Bottoms; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to bed bottoms, and has for an object to providea bed bottom of springs with improved structure permitting the raisingor tilting of one end of the spring fabric.

A further object of the invention is to provide a frame slidably hingedupon the main frame of the bed bottom, which said main frame carries aportion of the sprin fabric with means for securing the hinged frame atvarious inclinations.

A further object of the invention is to provide in a spring fabric a rodextending about the outer edge of such spring fabric with sliding jointspermitting one portion of the frame to move angularly relative to themain frame.

With these and other objects in View, the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the drawinosz-Figure 1 is a View of the improved bed bottom in edgeelevation with the end frame section raised to an inclination. Fig. 2 isa view in edge elevation of the bed bottom with the end hinged sectionlowered to a plane with the main section. Fig. 3 is a top plan View ofthe bed bottom showing at one corner springs secured thereon but removedfrom the remainder of the frame for the purpose of clearness ofillustration.

Like characters of reference designate corresponding parts throughoutthe several views.

The bed bottom which forms the subjectmatter of this application is madeup of side rods 10 and transverse strips 11 rigidly connected therewithand extending between the said side rods 10. The transverse strips 11are also preferably strengthened by an underlying longitudinal strip 12properly spacin such transverse strips and rigidly secure to suchstrips. The strips 11 do not cover the entire length of the side rods 10but at one end several of such strips are omitted with an end strip 13at the extremities of such side rods for the purpose of properlysecuring them together and spacing them apart.

Slidably mounted upon the side rods 10 are blocks 14 to which arepivoted arms 15 as at 16 and between such arms 15 strips 17 are rigidlysecured similar to the strips 11 and also extending transversely of thebed bottom. The frame made up of the arms 15 and transverse strips 17 isfurther strengthened by inclined braces 18 as indicated.

Rigidly secured to the side rails 10 are blocks 19 connected by means ofa rod 20 with links 21 pivotally surrounding such rod 20 and hinged inears 22 carried by the strip 17 nearest the pivots 16. i It will beapparent that when the frame composed of the arm 15 and strip 17 ismoved upon the pivot 16 the strip 17 will describe an arc about the rod20 as a center. This will cause the blocks 14 to slide along the siderails 10 as indicated at Figs. 1 and 2.

Rigidly secured to the arm 15 are blocks 23 with a rod 24 extendingacross and pivoted in such blocks. Adjacent the ends of the rod 24 pawls25 are rigidly connected with such rod and provided with teeth 25positioned to engage upon the rod 20 to hold the frame consisting of thearms 15 and strip 17 in an inclined position as shown at Fig. 1.

The structure thus described comprises the bed bottom proper upon whichis constructed a spring fabric composed of coiled springs 26 havingtheir lower coils inserted through openings in the transverse strips 11as indicated at 27 in Fig. 3 and connected by rings 27 and links 28 and29 also as indicated at Fig. 3.

About the top of the spring fabric is a main frame 30 terminatingadjacent the normal position of the blocks 14 in eyes 31 while anauxiliary frame 32 is similarly secured to the spring fabric carried bythe frame consisting of the arms 15 and transverse strip 17 with theextremities of such frame as indicated at 33 inserted through the eyes31 and slidable therein.

It will be apparent then that as the frame Y consisting of the arms land cross pieces 17 is raised it will be controlled in its mo-vement bythe links 2l so that the blocks 14:

will slide upon the frame 10 While the frame.

32 is permitted a hinging movement and also a sliding movement as may benecessary by reason of its extremity 33 passing through the eyes 3l. Theposition of the end frame or head rest having been secured is retainedby reason of the teeth Q5 engaging upon the rod 20 and as bot-h of thepawls 25 are rigidly secured to the rod 24C the manipulation of one ofsuch pawls will likewise control tlie other.

What we claim is l. In a bed bottom, a main frame, an auxiliary frameSlidably hinged to the main frame, a spring fabric erected upon theframes, a rod forming a frame about the spring fabric and a slidingjoint in the last-mentioned frame.

2. In a bed bottom, a main frame, a tilting frame hinged to the mainframe, a spring fabric erected upon the frames, a

- rod partially surrounding the fabric and provided with eyes and a rodsurrounding the remainder of said fabric and provided with extremitiesinserted through the eyes.

3. In a bed bottom, a frame, a spring fabric carried thereby, a rodarranged substantially parallel with the frame, a sliding member carriedby the rod, a member rigidly carried thereby, a tiltable Sectionincluding a spring fabric pivoted to the sliding member, an adjustablesupporting device connected with the tiltable section, means secured tothe rigidly mounted member and arranged to be engaged by the adjustabledevice, a rod connected with one portion of the spring fabric, a rodconnected with the fabric carried by the tiltable section, and means forforming a sliding connection between the two rods carried by the fabric.

In testimony whereof we aflix our signatures in presence of twowitnesses.v
